This study uses implementation fidelity data from PreK to 1st grade in the Boston Public Schools (BPS) to measure instructional alignment and examine whether stronger alignment is associated with sustained benefits of BPS PreK on children's language, literacy, and math skills through first grade. The study includes N = 498 students (mean age =…

Purpose: Dialect-shifting has shown promise as an effective way to improve academic outcomes of students who speak nonmainstream dialects such as African American English (AAE); however, limited studies have examined the impacts of an interprofessional approach with multiple instructional methods. In this study, we developed a dialect-shifting…

Purpose: Many children begin school with limited vocabularies, placing them at a high risk of academic difficulties. The goal of this study was to examine the effects of a vocabulary intervention program, "Story Friends," designed to improve vocabulary knowledge of at-risk preschool children. Method: Twenty-four early-childhood…

A classroom randomized trial (n = 31 classrooms) was conducted using the Second Step Early Learning (SSEL) curriculum compared to usual curricula. Head Start and community preschool classrooms enrolling low income children were randomly assigned to deliver SSEL (n = 16) or usual curricula (n = 15). Data are reported for four year olds…

The "MTP-Math/Science" curricula specifically target the teaching and learning of children at risk of early school failure, a population for whom achievement gaps in mathematics and science are visible even in Pre-K years. "MTP-Math" is based on Focal Areas defined by the National Council of Teachers of Mathematics (NCTM)…

The main objective of the overall Targeted Reading Intervention (TRI) was to help the classroom teacher acquire the key reading diagnostic strategies (e.g., Cooter, 2003; Desimone, 2009; Garet et al., 2001; Timperley & Phillips, 2003) relevant to K-1 struggling readers (e.g., Desimone, 2009; Garet et al., 2001; Guskey, 2002; Joyce &…

This research investigated the effects of two contrasting pre-k curricula, relative to practice as usual, on subsequent academic achievement. One curriculum had a strong literacy focus, the other was a less didactic "developmentally appropriate" curriculum that allowed children to have more influence on classroom activities. The purpose…
